Amagqabi Yellow izithole setumato? Ndifumane isigqibo seengcinga

Watyala izithole, anyamekele kuye, ngokuba ubunamanzi kakuhle, kodwa xa wafumanisa ukuba amagqabi tyheli xa izithole yetumato. Le izityalo isilumkiso sokuqala, kwenzeka ntoni ukuba kukho into engalunganga. Kubalulekile ukuba ukunikela ingqalelo, ukuba kwixesha elizayo abafuni ukuba kutshabalale libe linye enkulu lokuvuna ezicwangcisiweyo.

thombo Kungani yellow

Kaninzi, abalimi kufuneka banyamezele nezahlukahlukeneyo izifo ezichaphazela isityalo. Noko ke, abaphengululi wayeqhuba uthotho eksperimenti wafumana ukuba amagqabi yellowing izithole itumata ngenxa yezizathu eziliqela.

- lobushushu Ukungazinzi, utshintsho ngequbuliso ezinokuchaphazela izithole. Ukubuyisela ekuqaleni ukuthobela imo umoya.

- Ukungabikho ukukhanya kungahle kuchaphazele amagqabi yellowing. Kwelanga kubalulekile ukuba ifotosinthesisi, ngoko ukwandisa ukufikelela yayo kwisityalo.

- Ukungabikho izondlo ezibalulekileyo emhlabeni ikhokelela izityalo singami ndawonye. Ukuze uphephe oku, baswayipha nje ukuchumisa umhlaba kunye izichumisi nitrogen aqulethe okanye cow umgquba (1:10).

Phambi kokutyala entsha imbewu itumata bachithe ugqatso nokusingatha kudala potassium permanganate (potassium permanganate). Nkqu isisombululo medium-amandla nga yokungenelela iimbewu arhente causative kunokwenzeka, kuya ukhuseleko olongezelelweyo, ukunciphisa kakhulu amathuba okuba nezifo. Loo isisombululo kunye isitshizi nokuba itshizwe namahlumela abatsha izithole.

Yellow "abadala" izithole

Ngamanye amaxesha, nasemva ekwenzeni wonke umsebenzi ulondolozo kuyimfuneko emva kokutyala izityalo emhlabeni ushiya tyheli xa izithole yetumato. Kulo mzekelo, ufuna ukukhangela oonobangela ezininzi amagqabi mthubi.

Ukuba isityalo licwangcisa kuphela amagqabi asezantsi yellowing, yinkqubo eqhelekileyo yendalo. Ngoko iitumato ukulahla sizinze ezingeyomfuneko kubo, ukuba bonke imikhosi kunye incindi waya ukuyilwa inflorescences kunye neziqhamo.

Le meko eyahlukileyo ukuba amagqabi yellowing izithole itumata elisezantsi kuphela kodwa engasentla yonke isityalo ejonge ababuthathaka ecubhukile. Isizathu sokuba oku kube ezinzwaneni (Fusarium). Eyona nkalo iphambili olwahlula isifo - baphuma eziqhekekileyo kwiindawo kunye blackening.

izityalo ezonakeleyo ukugcina akukho msebenzi elide, ngoko ukumba phezulu, butshise, izithole ezishiyekileyo kangcono iimveliso zebhayoloji okuthintela izifo. Ukuze yokungenelela umhlaba, yongeza isichumiso esisityebi potassium, iphosphate.

Nkqu iintlobo kakhulu iitumato ukuba lungakhuseleki kwi izifo ezifana ezifana yonakalise kade. Imbonakalo amabala emdaka amagqabi, yellowing kunye omiswe of ubungqina bokuba sityalo abanesi sifo. Intsholongwane ingaba lula okuphakamileyo overwinter emhlabeni kumalungu yezityalo, kunye entwasahlobo kuchaphazela izithole. In (amanzi zokunkcenkceshela ukusetyenziswa ithontsi) ukuthintela inkqubo sifo iitumato arhente fungicidal, Bordeaux umxube, kwaye kananjalo ukunciphisa ukufuma komhlaba.

Khumbula, kungcono ukuthintela ukwenzeka sifo, kunokuba ukubusiphula. kwangexesha izithole itumata unakekelwa eyiyo aya kukuvumela ukuba babuthe isivuno efaka.
